The forming element for dievertical loops 11 comprises thepart 21 whichvprojects laterally from' the upstanding portion 220f a member 23, best shown in Figsutlandd, and

forming a part of a lever supportingbracket.

The remaining portion of thebraclr-et comprises the-upstanding part-Q lpcarried by a member 25 upon which the portion 23025 the bracket rests. Portions 23. and 25 are slotted .at 26to receive a bolt 2'? extending through the base 13 and permitting the loop forming element 21 to be adjusted inwardly and outwardly to correspond to the :adjustme'ntsof the upstanding loop forming element 15 -116 when the latter is adjusted ztO varythe; size ofthe loops-10.1:The lever 28 for bending the {wire about the member 21 to form the verticalloop 11 Vhasits inner end pivotallydlsposed between the upstanding-portlons 22' and 24.- of the lever supporting bracket: The lever carries a member 29;provided with'an offset portion 30 having'la groove "31 therein for receivlng the wire when the lever 1s swung from the positionshown in Fig; 5 to that showninFig.6. "o The' lever for bendingthe wire about the forming element 15-16 to pronuce the'horizontal loops 10' is indicated-at 32:and has its inner end resting on a support 33 on thebase 13 andpivotally connected with a bolt, .34 eX- tending through the supportand'the base, as shown in Fig. 5. Adjustably secured onthe lever is a member 35 havingethereon an upstanding wire bending and positioning ele-- ment 36, the wlreengaglng edge 37 of which 1s provided with anotch38 forreceivlngthe portion 10% of rthewire gwhen bending it about the elements-15- 16, to form the loops 10; The edge 3710f the bending element '36 is. preferably inclined .aaslight amount with shown.

ing elem ent 36 is arranged to swing upon the lever 32 about the axis of a pivot bolt 39 whereby. to adjust the wire bending V element to "the proper angle with respect to the wire forming elements 1516 in the different positions of adjustment thereof.' When proper position by a bolt 10 e'iztending through the as shown in Fig.9 1." l 1 5 One of the members for supporting the wire -during"the bending operations comprises an angular shaped bracket having a horizontal portion 42 restmg upon the base 13, andnn upstanding portion 43 carrying a member jfor receiving and supporting the -;lo0ped portions '11 of the wlre, as shown in 'F1'gsh3' and' 4c. The bracliet is ad ustable upon-the base toward and from the forming element 21 to accommodate the varying slzes off'the l oops lQ s aid bracket being held in the desired position by a bolt 45 extending through the base 1 ,-Fig.' a. .1

" Additional .supportlng means'for the wlre isprovidedin the form of a pair of screws I 47 disposed adjacent the forming element "155- 16 and threaded in the supporting members therefor indie ted at 17 and 18, respectively. The' lower ends of the screws preferably extended within slots formed in the base -13, not shown, which permit the screws to be moved Wlth the formmg elements when the latter areadjusted to provide for the formation of loops of ditlerent sizes, Relatively fine adjustment of the screws can be 'easily'efl'ected by employing a screw driver to turn the same in order to obtainaceurate distances in a vertical direction' ibetwe'en the ends of the screws and the wire forming and supporting elements 21 andfl i respectlvelyr These ad ustments are made necessary in ordertoinaintain the wire improper relation with respect to other supporting parts therefor, and particularly the parts 21 and 44; Furthermore, when the size ofthe wire is to be in'creasedor decreased the screws 47 will be adjusted accordingly,

since-it is preferred to maintain the support ing parts 21and lelflat a fixed distance from the base 13. Furthermore, if desired, the sizexofthe supporting p1ns21 and 4a maybe ,varled, depending onthediameter ofthe wire and the distance to be allowedbetween the upper and lower portions of the loopsl'l.

An additional support for thelinltis provided n the form of an ad ustable screw suitably mounted for vertical adjustment on thebase, as for example by threading it 1516, but is preferably solocated mo form a rest for one of the side portions of the'loop carried by the supporting "pin44, as shown in Fig. 3. The height of the screw 48 will be regulated to correspond tolthat ofthescrews 47 in order to maintain the looped portion of the wire in the shown in Fig. 4.

When the first 7 made full size, as shown'at the lefto'fFig. 3, the extreme end portion of thewireiis' bent to like POItlODi the same, is inserted upon Icthe support 44 with the remainingv portion of the wire extending over thebase,"as shown by dotted lines inFig. 3,,reacly' tobe bentar'ound the forming elements f16,"as (describedhereinafter, However-hf: the first of thejhori; zontal loops to be formed is to be of less width;

As stated above, upon com pletion of the main'loop's the remaining portionlQa of the wire maybe bent onja different machine tocomp'letethehalf loop, as indicated at 12 in Fig; 8. a
